Intrepid V6-201 3.3L (1995)
Speedometer Module: Description and Operation
The speedometer receives its information across the CCD Bus from the Body Control Module (BCM). Information on vehicle speed is transmitted from
the Powertrain Control Module (PCM) across the CCD Bus to the BCM.
The PCM receives its information on vehicle speed on the G7 circuit from the Transmission Control Module (TCM).
The BCM calculates the position of the speedometer pointer based on the input from the PCM and adjusts the position of the gauge pointer as necessary.
This signal is sent over the CCD Bus to the instrument cluster.
